Electronic Device and Operation Method Thereof

1. An electronic device comprising: a display; and at least one processor operatively coupled to the display and configured to: identify an operation state of the display, control the display to display a first UI based on a first object in response to the identifying that the operation state is a first state, and control the display to display a second UI based on the first object and a second object associated with the first object, at a portion adjacent to the first object, in response to the identifying that the operation state is a second state.

2. The electronic device of claim 1 , wherein the first object includes an application icon, and the second object includes a mini application associated with the first object.

3. The electronic device of claim 1 , wherein the display comprises at least two areas, and the at least one processor is further configured to identify the operation state of the display based on operation states of the at least two areas of the display.

4. The electronic device of claim 3 , wherein the at least one processor is further configured to: detect a state change from the first state to the second state in response to the operation states of the at least two areas of the display, and increase a size of an empty space between the first object and another object, and display the second object in the empty space, based on the detecting of the state change.

5. The electronic device of claim 4 , wherein the at least one processor is further configured to, based on the detecting of the state change from the first state to the second state, display a switching effect using a widget shadow through the empty space between the first object and the other object, corresponding to a direction in which the state change proceeds.

6. The electronic device of claim 3 , wherein the at least one processor is further configured to: detect a state change from the second state to the first state in response to the operation states of the at least two areas of the display, and decrease a size of an empty area between the first object and another object and discontinue the display of the second object, based on the detecting of the state change.

7. The electronic device of claim 6 , wherein the at least one processor is further configured to, based on the detecting of the state change from the second state to the first state, allocate the first object to a first area of the at least two areas of the display and allocate the second object to a second area of the at least two areas of the display.

8. The electronic device of claim 3 , wherein the at least one processor is further configured to control the display to display the first object on a first area of the at least two areas of the display, and display the second object on a second area of the at least two areas of the display in response to the identifying that the operation state is the first state.

9. The electronic device of claim 8 , wherein the at least one processor is further configured to detect a flipping of the electronic device and deactivate one of the first area and the second area, based on the detecting of the flipping.

10. The electronic device of claim 1 , wherein the at least one processor is further configured to identify the second object associated with the first object, and provide, as the second object, an empty space or an image obtained by a capturing of a last execution screen of an application corresponding to the first object based on the identifying of the second object.

11. The electronic device of claim 3 , wherein the at least one processor is further configured to: identify the second object from objects displayed on one of the at least two areas of the display where the first object is not displayed, and provide, as the second object, the identified object from the objects displayed on the one of the at least two areas of the display, an empty space corresponding to the second object, or an image obtained by capturing a last execution screen of an application corresponding to the first object based on identifying the second object.

12. An operation method of an electronic device, the operation method comprising: identifying an operation state of a display; displaying a first user interface (UI) based on a first object, in response to the identifying that the operation state is a first state; and displaying a second UI based on the first object and a second object associated with the first object, at a portion adjacent to the first object in response to the identifying that the operation state is a second state.

13. The operation method of claim 12 , wherein the first object includes an application icon, and wherein the second object includes a mini application associated with the first object.

14. The operation method of claim 12 , wherein the identifying of the operation state comprises identifying the operation state of the display based on operation states of at least two areas of the display.

15. The operation method of claim 14 , further comprising: detecting a state change from the first state to the second state in response to the operation states of the at least two areas of the display; and increasing a size of an empty space between the first object and another object and displaying the second object in the empty space, based on the detecting of the state change, wherein the displaying of the second object comprises, based on the detecting of the state change from the first state to the second state, displaying a switching effect using a widget shadow through the empty space between the first and the other object, corresponding to a direction in which the state change proceeds.

16. The operation method of claim 14 , further comprising: detecting a state change from the second state to the first state in response to the state changes of the at least two areas of the display; and decreasing a size of an empty space between the first object and another object and discontinuing the display of the second object based on the detecting of the state change, wherein the displaying of the first UI comprises: allocating the first object to a first area of the at least two areas of the display, and allocating the second object to a second area of the at least two areas of the display.

17. The operation method of claim 14 , wherein the displaying of the first UI comprises: displaying the first object on a first area of the at least two areas of the display and displaying the second object on a second area of the at least two areas of the display in response to the identifying that the operation state is the first state.

18. The operation method of claim 17 , wherein the displaying of the first UI comprises detecting a flipping of the electronic device and deactivating one of the first area and the second area based on the detecting of the flipping.

19. The operation method of claim 12 , wherein the displaying of the second UI comprises identifying the second object associated with the first object, and providing, as the second object, an empty space or an image obtained by a capturing a last execution screen of an application corresponding to the first object based on the identifying of the second object.

20. The operation method of claim 14 , wherein the displaying of the second UI comprises: identifying the second object from objects displayed on one of the at least two areas of the display where the first object is not displayed; and providing, as the second object, the identified object from the objects displayed on the one of the at least two areas of the display, an empty space corresponding to the second object, or an image obtained by capturing a last execution screen of an application corresponding to the first object based on identifying the second object.
